Winchester Bismuth 20GA 3" #4 Shot 1oz – 15 Round Box

Winchester Bismuth shotshells deliver non-toxic performance for waterfowl hunters who want steel-beating patterns without the density penalties. This 20-gauge load uses a full 1 ounce of #4 bismuth shot in a 3-inch hull—bismuth's 9.6 g/cc density sits between steel and lead, offering better downrange energy retention and tighter pattern efficiency than steel while remaining safe in older fixed-choke barrels not rated for steel shot. The #4 shot size balances pellet count and striking energy for ducks at typical decoying ranges and works well on pass-shooting opportunities over timber or flooded fields.

These shells are loaded with a clean-burning powder charge optimized for smooth cycling in gas-operated semi-autos and reliable ignition in all weather. The bismuth pellets are buffered to resist deformation during setback, preserving roundness for consistent flight. Available in 15-round boxes. Safe for use in any shotgun proofed for standard or magnum loads, including vintage doubles and pumps with fixed chokes where steel shot is prohibited.
